Hate your job? NASA wants you to work on Mars

US space agency NASA has just released a series of retro recruitment posters that advertise potential positions it may one day need filled on Mars.

First commissioned in 2009 for an exhibit at the Kennedy Space Center Visitor's Complex, the colorful posters feature "advertisements" for teachers, surveyors and farmers, among a raft of other occupations.

NASA has started using posters like these to help people imagine what a future in space may look like. Earlier this year, the agency released a set of prints promoting space tourism. They can all be downloaded for free from the NASA website.

However, it may be a while before all these people are actually needed. NASA released its three-step Journey to Mars plan to colonize the Red Planet in 2015, and doesn't envision having people living and working in colonies until 2030.
